The effect of exercise in the sense of position remains controversial to explain, and further research is necessary. Some studies suggest a decline of the sense of velocity and position sense after an isometric contraction exercise protocol. Indeed, there is a common feeling of awkwardness and clumsiness after intense exercise that is not only muscle weakness, but also a lesser certainty about the placement of the fatigued limbs in the absence of vision <ref name=”2”></ref> <ref name=”5”></ref>. | The effect of exercise in the sense of position remains controversial to explain, and further research is necessary.

There is also the suggestion that the effort that is required to maintain the position of a limb against the force of gravity is the element that provides the positional cue, although some studies contradict this sense of effort hypothesis. Moreover, data supports the view that muscle spindle would be responsible for the sense of movement, not being sensitive to exercise disruption <ref name=”5”></ref>. | There is also the suggestion that the effort that is required to maintain the position of a limb against the force of gravity is the element that provides the positional cue, although some studies contradict this sense of effort hypothesis.

==Proprioception and virtual reality== | |||
Proprioception allows the formation of a mental model, describing the spatial and relational dispositional of the body and its parts. A virtual reality system needs that the normal proprioceptive data that is used to form a mental model of the body be overlaid with sensory data that is supplied by the computer-generated displays. For an effective virtual reality, it is fundamental that there is consistency between proprioceptive information and sensory feedback. This is done by the correct capturing of the movement of the user, and simulating it in the virtual environment, in order to increase a sense of immersion <ref> Slater, M., Usoh, M. and Steed, A. (1995). Taking steps: the influence of a walking technique on presence in virtual reality. ACM Transactions on Computer_Human Interaction, 2(3): 201-219</ref>. Also, according to Mine (1997), “providing a real-world frame of reference in which to operate and a more direct and precise sense of control, proprioception helps to compensate for the lack of haptic feedback in virtual-environment interaction.” <ref> Mine, M.
